Encryption malware question.

[inachu]

If I have a hard drive that is already encrypted via TPM Then the malware would fail right?

I do not think a drive can be encrypted twice.

No, the malware would not fail. You can encrypt files more than once.

Most common encryption schemes today encrypt through multiple rounds, so yes you can encrypt data many times.

If you want to avoid just get an apple computer.

Truecrypt can use a cascade of ciphers.

Sandboxie FTW!

There's no technical limit to how many times data can be encrypted, only practical ones (time, energy, money, patience). That being said, using multiple ciphers/keys is unnecessary. All you're going to accomplish by using a cascade is to tank your I/O performance and waste CPU cycles, especially if you have a processor that supports AES-NI. AES-256 is good enough for anything in this universe.
